Lo instale en mi CNC 3018Pro y el eje X se mueve en dirección opuesta. Espero el vendedor me pueda compartir un instructivo de configuración. Aparte el Software GRBL Controller lo marca como Estado: Desconocido, aun así se puede mover los ejes de manera manual pero no es ideal para usarlo directamente (plug and play).

First one was defective. Replacement process was a bit time consuming as it involved having to send a video of the failures. It was replaced but I have not tried the new one as I have other machine issues to contend with first. The newest version does appear to have some improvements though. If it works I will upgrade the stars.
